To keep this an apples to apples comparison, assume both rifles have the following:
Same factory short action
26 inch barrel from the same barrel maker.
a twist appropriate for 75 grain bullet
launch a 75 grain bullet at 3350 FPS
Long Range varmint hunting (600 yards) could use a larger/ heavier bullet because of wind
When you start taking varments at these distances you can use a 6mm,6.5mm or even a 7
mm bullet because conditions will not always be perfect and the smaller bullets will give you
fits trying to out smart the wind.
Any of these calibers in a 308 size case or smaller will work and recoil is not an issue.
The really hot 22 cal rounds are tough on barrels with high use rates so if you keep the
velocity at around 3000 +or- barrel life is not to bad.
Just my opinion
